ABSTRACT

Objective@#High vagal paralysis (HVP) is a type of vocal-fold paralysis, associated with discoordination of the pharyngeal musculature, and the failure of the cricopharyngeus muscle to relax, leading to swallowing disability. We evaluated the difference between the functional results of office-based injection laryngoplasty and medialization thyroplasty in patients with unilateral vocal cord paralysis caused by HVP. @*Methods@#A retrospective review of 28 patients following laryngoplasty with HVP was performed. Pre- and posttreatment swallowing and voice functions were reviewed. @*Results@#Seventeen patients underwent injection laryngoplasties, while 11 received medialization thyroplasties. In both groups, all except one patient who received medialization thyroplasty recovered their ability to swallow after appropriate procedures (100% vs. 91%). An acoustic analysis demonstrated significant changes in shimmer, noiseto-harmonic ratio, and maximum phonation time (MPT) in the injection laryngoplasty group, whereas significant changes in jitter and MPT were observed in the medialization thyroplasty group. @*Conclusion@#Office-based injection laryngoplasty was found to be an effective and reliable therapy for improving swallowing and voice function in patients with HVP, compared to medialization thyroplasty.

ABSTRACT

Primary squamous cell carcinomas arising from the thyroid is an extremely rare malignancy, which clinically can invade the larynx and trachea. In such an event, thyroidectomy with en bloc resection and reconstruction is the treatment of choice. However, laryngotracheal reconstruction remains a challenge and no ideal reconstruction has yet been established. Herein, we report a case of a thyroid squamous cell carcinoma invading the laryngotrachea. The tumor was completely resected surgically, including the laryngotrachea wall, which was reconstructed with a radial forearm free flap. The patient was decannulated one year after surgery and no evidence of disease was detected two years after surgery.

ABSTRACT

The aim of this study was to develop evidence-based recommendations for determining the surgical extent in patients with locally invasive differentiated thyroid cancer (DTC). Locally invasive DTC with gross extrathyroidal extension invading surrounding anatomical structures may lead to several functional deficits and poor oncological outcomes. At present, the optimal extent of surgery in locally invasive DTC remains a matter of debate, and there are no adequate guidelines. On October 8, 2021, four experts searched the PubMed, Embase, and Cochrane Library databases; the identified papers were reviewed by 39 experts in thyroid and head and neck surgery. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the quality of evidence, and to develop and report recommendations. The strength of a recommendation reflects the confidence of a guideline panel that the desirable effects of an intervention outweigh any undesirable effects, across all patients for whom the recommendation is applicable. After completing the draft guidelines, Delphi questionnaires were completed by members of the Korean Society of Head and Neck Surgery. Twenty-seven evidence-based recommendations were made for several factors, including the preoperative workup; surgical extent of thyroidectomy; surgery for cancer invading the strap muscles, recurrent laryngeal nerve, laryngeal framework, trachea, or esophagus; and surgery for patients with central and lateral cervical lymph node involvement. Evidence-based guidelines were devised to help clinicians make safer and more efficient clinical decisions for the optimal surgical treatment of patients with locally invasive DTC.

ABSTRACT

The coronavirus disease 2019 (COVID-19) pandemic caused by the novel severe acute respiratory syndrome coronavirus-2 has upended the world of otolaryngology. After COVID-19 infection, patients experience various complication of symptoms due to injury of the larynx and lung/ respiratory system. Regardless of the patient’s severity, patients can experience several complications including dysphonia, vocal cord paralysis/paresis and sensory neuropathy. An emerging role for otolaryngologists in the coming weeks and months is the management of laryngeal complications of COVID-19. This review is intended to describe laryngeal complications in patients recovering from COVID-19 infection.

ABSTRACT

Background/Objectives@#The aim of this national population-based retrospective study was to analyze the status and treatment outcome in patients with hypopharyngeal cancer.Materials & Methods: Participants were included in the KNHIS national sample cohort who received a KNHIS health check-up in 2008 and 2009, and we followed these individuals until 2017. Patients were defined as having hypopharynx cancer if they had admissions records for hypopharynx cancer in their national health insurance data from 2010 to 2017. @*Results@#The study cohort included 3,922 patients. According to our nationwide data, 3,533(90.1%) were male with a median age of 65.03±11.04 years at the time of diagnosis. Among parametric models for hypopharyngeal cancer prognosis, old age (Hazard ratio [HR]:1.92; 95% confidence interval[CI]:1.76-2.09), female (HR:0.77; 95% CI:0.66-0.89), and low socioeconomic status (HR:1.216; 95% CI:1.114-1.327) were significantly associated with survival. Compared with concurrent chemoradiotherapy, patients who received no treatment (HR, 1.88; 95% CI, 1.31-2.70), neoadjuvant chemotherapy followed by surgery (HR, 1.21; 95% CI, 1.04-1.41), and chemotherapy alone (HR, 1.16; 95% CI, 1.03-1.27) showed poor prognosis in hypopharyngeal cancer. @*Conclusion@#Our data indicated that age, sex, and income were significant predictors of lifetime survival in patients with hypopharyngeal cancer. Treatment modalities were also associated with prognosis. The data have implications for treatment investigations and prevention strategies.

ABSTRACT

Purpose@#The incidence of human papillomavirus (HPV)-related oropharyngeal cancer (OPC) has increased, and staging and optimal therapeutic approaches are challenging. A questionnaire survey was conducted to investigate the controversial treatment policy of stage T2 OPC according to the N category and determine the opinions of multidisciplinary experts in Korea. @*Materials and Methods@#Five OPC scenarios were developed by the Subcommittee on Oropharyngeal Treatment Guidelines of the Korean Society for Head and Neck Oncology and distributed to experts of multidisciplinary treatment hospitals. @*Results@#Sixty-five experts from 45 institutions responded. For the HPV-positive T2N0M0 scenario, 67.7% of respondents selected surgery followed by definitive concurrent chemoradiotherapy (CCRT) or radiotherapy alone. For the T2N1M0 HPV-positive scenario, there was a notable difference in the selection of primary treatment by expert specialty; 53.9% of respondents selected surgery and 39.8% selected definitive CCRT as the primary treatment. For the T2N3M0 advanced HPV-positive scenario, 50.0% of respondents selected CCRT and 33.3% considered induction chemotherapy (IC) as the primary treatment. CCRT and IC were significantly more frequently selected for the HPV-related OPC cases (p=0.010). The interdepartmental variability showed that the head and neck surgeons and medical oncologists favored surgery, whereas the radiation oncologists preferably selected definitive CCRT (p < 0.001). @*Conclusion@#In this study, surgery was preferred for lymph node-negative OPC, and as lymph node metastasis progressed, CCRT tended to be preferred, and IC was administered. Clinical practice patterns by stage and HPV status showed differences according to expert specialty. Multidisciplinary consensus guidelines will be essential in the future.

ABSTRACT

Purpose@#To investigate the relationship between hearing loss and cognitive disorder with memory dysfunction in South Korea using data from the Korean Health Insurance claims database for 2009–2015. @*Materials and Methods@#We analyzed cross-sectional data of 66-year-old individuals who completed the Korea National Health and Nutrition Examination Surveys. Auditory function was evaluated using pure-tone audiometric testing. Cognitive disorder with memory dysfunction was assessed using standardized scores of the Prescreening Korean Dementia Screening Questionnaire. @*Results@#Among 1815835 participants at the age of 66 years, the prevalence of unilateral hearing loss was 5.84%, and that of bilateral hearing loss was 3.40%. The normal cognitive group comprised 86.35% of the participants, and the high-risk group for cognitive disorder with memory dysfunction totaled 13.65% of the participants. The bilateral hearing loss group had the highest percentage of subjects who responded “sometimes or frequently” to all five questions about cognitive disorder with memory dysfunction, compared to the normal hearing group or the unilateral hearing loss group. After adjusting for sex, smoking status, alcohol intake, exercise, income, diabetes, hypertension, dyslipidemia, and depression, the odds ratios for cognitive disorder with memory dysfunction was 1.183 [95% confidence interval (CI): 1.163–1.203] for bilateral hearing loss and 1.141 (95% CI: 1.126–1.156) for unilateral hearing loss, compared to the normal cognitive group. @*Conclusion@#Hearing loss has a significant effect on cognitive function in the Korean population. In our study, individuals with bilateral hearing loss showed poorer cognitive function than those with unilateral hearing loss.

ABSTRACT

Background@#High-risk (HR) human papillomavirus (HPV) is found in a subset of head and neck (HN) squamous cell carcinomas (SCCs). For oropharyngeal SCCs, HR HPV positivity is known to be associated with good prognosis, and a separate staging system for HPV-associated carcinomas using p16 immunohistochemistry (IHC) as a surrogate test has been adopted in the 8th American Joint Committee on Cancer staging system. We examined the HR HPV status and the genotype distribution in five HN subsites. @*Methods@#Formalin-fixed paraffin-embedded tissue sections were used for p16 IHC and DNA extraction. HPV DNA detection and genotyping were done employing either a DNA chip-based or real-time polymerase chain reaction–based method. @*Results@#During 2011–2019, a total of 466 SCCs were tested for HPV DNA with 34.1% positivity for HR HPV. Among HN subsites, the oropharynx showed the highest HR HPV prevalence (149/205, 75.1%), followed by the sinonasal tract (3/14, 21.4%), larynx (5/43, 11.6%), hypopharynx (1/38, 2.6%), and oral cavity (1/166, 0.6%). The most common HPV genotype was HPV16 (84.3%) followed by HPV35 (6.9%) and HPV33 (4.4%). Compared with HR HPV status, the sensitivity and specificity of p16 IHC were 98.6% and 94.3% for the oropharynx, and 99.2% and 93.8% for the tonsil, respectively. @*Conclusions@#Using a Korean dataset, we confirmed that HR HPV is most frequently detected in oropharyngeal SCCs. p16 positivity showed a good concordance with HR HPV DNA for oropharyngeal and especially tonsillar carcinomas. The use of p16 IHC may further be extended to predict HR HPV positivity in sinonasal tract SCCs.

ABSTRACT

Background and Objectives@#To investigate the prognostic value of the neutrophil to lymphocyte ratio (NLR) in patients with head and neck squamous cell cancer (HNSCC).Subjects and Method Clinical data from 259 patients with HNSCC were collected retrospectively. NLR was adopted as potential prognostic biomarkers. @*Results@#NLR was associated with cancer recurrence (p=0.002 and p<0.001, respectively). Patients with a NLR >2.15 had significantly decreased 5-year disease specific survival (DSS) based on the Kaplan-Meier survival curves (p<0.001 and p=0.029, respectively). The Multivariate Cox regression analysis confirmed a significant association between 5-year DSS and the NLR (using 2.15 as the cut-off; hazard ratio, 1.852; 95% confidence interval, 1.237-2.771; p= 0.003). @*Conclusion@#A NLR cut-off value ≥2.15 was associated with adverse outcomes in patients with HNSCC.

ABSTRACT

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to “surgical management of oral cancer” published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrandomized Studies) and AMSTAR (A Measurement Tool to Assess the Methodological Quality of Systematic Reviews). Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. Additional directives are provided as expert opinions and Delphi questionnaire when insufficient evidence existed. The Committee developed 68 evidence-based recommendations in 34 categories intended to assist clinicians and patients and counselors, and health policy-makers. Proper surgical treatment selection for oral cancer, which is directed by patient- and subsite-specific factors, remains the greatest predictor of successful treatment outcomes. These guidelines are intended for use in conjunction with the individual patient's treatment goals.

ABSTRACT

BACKGROUND: The aim of this study was to investigate the association between sleep duration and dizziness in a representative Korean population. METHODS: We analyzed data from the Korea National Health and Nutrition Examination Surveys (2010–2012). A total of 12,499 adults who completed otolaryngologic examinations were evaluated. RESULTS: Both men and women with severely short sleep duration (≤ 5 hours) and severely long sleep duration (≥ 9 hours) tended to have higher dizziness prevalence. However, the adjusted odds ratio (OR) for sleep duration was only significant in women with dizziness after adjusting for confounders. Compared to that in an optimal sleep group (6–8 hr/day), the OR (95% confidence interval) for dizziness prevalence after adjusting for age and health behaviors (body mass index, smoking habit, alcohol consumption, level of exercise, metabolic syndrome, and tinnitus) was 1.473 (1.194–1.818) for the severely short sleep group (≤ 5 hr/day) and 1.472 (1.078–2.009) for the severely long sleep group (≥ 9 hr/day) only in women. CONCLUSION: In the Korean population, dizziness was associated with shorter or longer sleep durations only among women. Further epidemiologic and experimental studies are necessary to clarify the impact of dizziness on sleep disorders.

ABSTRACT

BACKGROUND AND OBJECTIVES: The aim of this study is verify the correlation between benign laryngeal mucosal disease and metabolic syndrome. MATERIALS AND METHOD: Data for patients diagnosed with benign laryngeal mucosal disease and metabolic syndrome from 2006 to 2015 were selected for analysis from the National Health Insurance Service database. RESULTS: The prevalence of Metabolic syndrome was 2,179,785 out of 6,437,051 patients (33.86%). The prevalence of benign laryngeal mucosal disease was 516,594 out of 6,437,051 patients (8.03%). Metabolic syndrome was a risk factor for benign laryngeal mucosal disease [hazard ratio: 0.99, 95% confidence interval: 0.984–0.997] after adjusting for age and other variables including age, gender, smoking status, alcohol intake, exercise, body mass index, and diabetes. The number of metabolic syndrome components was also risk factor. CONCLUSION: Metabolic syndrome was related to the incidence of benign laryngeal mucosal disease. However this correlation did not seem to be high.

ABSTRACT

BACKGROUND AND OBJECTIVES: This study investigated the relationship between reflux symptom index (RSI) and psychiatric problems such as depression, somatization, and anxiety. SUBJECTS AND METHOD: We prospectively analyzed 231 patients with symptoms with laryngopharyngeal reflux (LPR) using the RSI and the reflux finding score. RESULTS: Seventy nine patients (34.2%) were diagnosed with LPR. A significant correlation was detected between the RSI and depression (18.4±8.3 vs. 12.3±7.0, p < 0.001), anxiety (19.5±8.5 vs. 13.0±7.3, p < 0.001), and somatization (19.2±9.1 vs. 13.6±7.5, p < 0.001). A multivariate analysis confirmed a significant association between heartburn and depression [odds ratio (OR): 1.241, 95% confidence interval (CI): 1.003–1.537, p=0.047], choking and anxiety (OR: 1.747, 95% CI: 1.297–2.352, p < 0.001), and choking and somatization (OR: 1.707, 95% CI: 1.248–2.336, p=0.001). CONCLUSION: Our preliminary results suggest that patients with high RSI may need to be carefully evaluated for psychiatric problems.

ABSTRACT

BACKGROUND AND OBJECTIVES: Laryngopharyngeal reflux disease (LPRD) is relatively common disease. N-acetyl cysteine (NAC) has both mucolytic and antioxidant effect, also may be beneficial in inflammatory airway diseases. The purpose of this study was to evaluate the efficacy and safety of inhaled NAC therapy in LPRD. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 525 LPRD patients at 12 medical centers. Finally 401 patients subjected to inhaled NAC therapy for 2 months were enrolled in the study. We analyzed the change of Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) after use of NAC for 4 weeks and 8 weeks in addition to the patient's compliance of the treatment. RESULTS: The RSI score significantly decreased from 19.87±6.34 to 12.78±6.93 after 4 weeks and to 10.65±7.47 after 8 weeks. The RFS score also significantly decreased from 9.29±3.4 to 7.17±3.41 after 4 weeks and to 6.1±3.73 after 8 weeks (p<0.05). During the treatment periods, 42 patients (10.4%) reported to have 80 episodes of discomfort. Throat discomfort (33%) and nausea (28%) were most common complaints, but the duration of discomfort was usually less than 4 weeks. CONCLUSION: Inhaled NAC treatment is highly effective for the reduction of both subjective and objective findings in LPRD patients. This study will provide the evidence of new treatment option for patients with LPRD. However, further studies will be needs to assess the real effect of inhaled NAC therapy as a standard treatment regimen of LPRD.

ABSTRACT

BACKGROUND AND OBJECTIVES: The effect of palliative injection laryngoplasty in cancer-related unilateral vocal cord paralysis patients on voice and swallowing function is uncertain and there are few previous studies of its suitability, benefits as a palliative treatment option. The purpose of this study is to confirm the objective results of voice and swallowing function after palliative office-based hyaluronic acid injection laryngoplasty in cancer-related unilateral vocal cord paralysis patients. MATERIALS AND METHOD: 36 patients who had unilateral vocal cord paralysis from non-thyroidal, extralaryngeal neoplasms were included in this study. To evaluate the clinical outcome, we analyzed perceptual GRBAS grading, acoustic analysis, aerodynamic study, Electroglottography (EGG), Voice Handicap Index (VHI-30) about voice function and disability rating scale (DRS), gastric tube dependency, aspiration pneumonia about swallowing function and 36-Item Short Form Survey version 2 (SF-36v2) about quality of life. RESULTS: In GRBAS scale, G (p < 0.001), R (p=0.004), B (p=0.001), A (p=0.011), and S (p=0.007) showed significant improvement. Jitter, shimmer, speaking fundamental frequency, maximal phonation time, VHI-30, DRS score, gastric tube dependency, aspiration pneumonia, and SF-36v2 were significantly improved after injection (p=0.016, p=0.011, p=0.045, p=0.005, p < 0.001, p < 0.001 p=0.003, p < 0.001, and p < 0.001 respectively). CONCLUSION: From this study we concluded office-based hyaluronic acid injection can be used as a useful palliative treatment option in cancer-related ill patients with unilateral vocal cord paralysis. Palliative hyaluronic acid injection laryngoplasty avoids the need for tube feeding, thus reducing the risk of aspiration pneumonia. These outcomes are accompanied by significant improvement in voice quality.

ABSTRACT

This study investigated the relationship between depression, somatization, anxiety, personality, and laryngopharyngeal reflux (LPR). We prospectively analyzed 231 patients with symptoms with LPR using the laryngopharyngeal reflux symptom index and the reflux finding score. Seventy nine (34.2%) patients were diagnosed with LPR. A significant correlation was detected between the presence of LPR and total scores on the Patient Health Questionnaire-9 (5.6±5.3 vs. 4.0±4.6, p=0.017) and the 7-item Generalized Anxiety Disorder Scale (4.3±4.9 vs. 3.0±4.5, p=0.041). LPR was significantly more frequent in those with depression than in those without (45.6% vs. 27.0%, p=0.004). A multivariate analysis confirmed a significant association between the presence of LPR and depression (odds ratio, 1.068; 95% confidence interval, 1.011–1.128; p=0.019). Our preliminary results suggest that patients with LPR may need to be carefully evaluated for depression.

ABSTRACT

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to develop clinical practice guidelines for the surgical treatment of laryngeal cancer. This Task Force conducted a systematic search of the EMBASE, MEDLINE, Cochrane Library, and KoreaMed databases to identify relevant articles, using search terms selected according to the key questions. Evidence-based recommendations were then created on the basis of these articles. An external expert review and Delphi questionnaire were applied to reach consensus regarding the recommendations. The resulting guidelines focus on the surgical treatment of laryngeal cancer with the assumption that surgery is the selected treatment modality after a multidisciplinary discussion in any context. These guidelines do not, therefore, address non-surgical treatment such as radiation therapy or chemotherapy. The committee developed 62 evidence-based recommendations in 32 categories intended to assist clinicians during management of patients with laryngeal cancer and patients with laryngeal cancer, and counselors and health policy-makers.

ABSTRACT

BACKGROUND AND OBJECTIVES: This study aimed to determine the dimensions of normal salivary and thyroid glands and assess their relationship with respect to age and sex using three-dimensional imaging in children. SUBJECTS AND METHOD: One hundred twenty patients were divided into four age groups: group 1 (0-5 years), group 2 (6-10 years), group 3 (11-15 years), and group 4 (16-20 years). The volume, thickness, width, and length of the each gland were measured. RESULTS: The parotid glands exhibited a growth spurt in group 2. There were no differences between genders for parameters of the parotid gland in groups 1, 2, and 3 except in group 4. The length of submandibular gland exhibited a monomodal growth pattern, which increased until 20-years-of-age. There was a significant difference of volume and thickness between the right and left thyroid gland in all groups. CONCLUSION: Volume and other parameters of the salivary and thyroid gland increase with age.
